7. Provide for expansion and contraction without detriment to appearance or performance.

8. Assemblies shall be free from rattles, wind whistles and noise due to thermal and structural movement and wind pressure.

9. Not Permitted: Vibration harmonics, wind whistles, noises caused by thermal movement, thermal movement transmitted to other building elements, loosening, weakening, or fracturing of attachments or components of system.

B. Performance Requirements:1. Air infiltration: Air leakage through fixed light areas of storefront shall not

exceed 0.06 cfm per square foot (0.0003 m3/sm2) of surface area when tested in accordance with ASTM E283 at differential static pressure of 6.24 psf (300 Pa).
